The original image

Captured on a starry night on the Pembrokeshire coast, this image combines the rugged scenery with the Milky Way and a small meteor to the top right of frame. Though it is in focus and composed pleasingly, there’s still some work to do. There’s quite a strong colour cast to the image, a very dark foreground with a lot of lost detail, and the Milky Way is very faint.

With a little time and Skylum’s incredible Luminar software, we can take process this shot into a portfolio quality image with punchier colours and properly show off the astronomical detail in the sky.

Step 1 – Foreground

Start with some AI Accent magic

My first step in most image edits is to use Luminar’s amazing AI Accent filter, a content-aware filter which analyses the image and automatically enhances it. Instantly, highlights are calmed down, details are brought out of the darkness, and colour tones are instantly improved.

If the colour tone is still not quite right, a subtle adjustment with Luminar’s Color Temperature filter will do the trick.

A subtle adjustment of the Foliage Enhancer will gently increase the luminosity and saturation of green tones in your image, instantly making the grass and moss become more visible.

Remove Color Cast

There’s still quite a strong purple tone to the foreground – if you examine the foliage you’ll notice that green grass and moss is just a little off-colour. Here, I use the Remove Color Cast filter to adjust this automatically. In doing so, we lose some brightness, but we can continue working on this.

Correct the horizon colours

Some lights can be seen on the horizon as we look east, which creates some interesting illumination but introduces some unwelcome colours to the frame. I use the Split Color Warmth filter to add just a touch of colour to this – brilliant white colours now appear golden, and some pink is added to the horizon’s glow.

Correcting the exposure manually

Our foreground is still quite dark, so I combine several filters to improve this. Turning up the brightness and slightly lowering the contrast in the Brightness / Contrast filter adjusts the whole image. Next, the Top & Bottom Lighting filter which does exactly as you’d expect – I add some lighting to the bottom of the image. Finally, boosting the whites and slightly darkening the blacks in Whites / Blacks to manually adjust the contrast.

Sharpening

Finally, a touch of sharpening, to add some definition between edges.

Foreground editing complete

Let’s review where we are so far.

Step 2 – Sky

Masking

Create a new Adjustment Layer, then add a new Gradient Mask. This allows you to select which area of image is affected by the filters on this adjustment layer. You’ll notice there is a band of glow near the horizon. Creating a gentle vertical gradient across this, ending at the horizon line, ensures all the brightest stars are affected. If you find your mask is adding too much, or not doing enough, you can always edit this mask later.

Accent AI

As before, a touch of Accent AI filter which will analyse and improve the sky detail, plus any manual colour correction using the Color Temperature filter. In this case, I chose to reintroduce just a touch of magenta as there are some subtle green tones in the darker areas of sky.

Turn up the lights

The Microstructure and Dramatic filters are superb choices to ramp up the night sky detail.

Correcting the tone and colours manually

Turning up the warms and bringing down the cools using the Split Color Warmth filter gives us rich purple and blue tones in the sky. Next, I manually adjust the overall contrast and tone using the Highlights / Shadows and Whites / Blacks filters – my goal here to to create more separation between the highlights of the stars and the darks of the surrounding sky.

Make the stars glow

To instantly add a magical glow and exposure to the stars, use the Soft Focus filter.

Subtly improve the colours

Just a touch of added Color Contrast to improve the colour tones in the sky.

Highlight the Milky Way

The High Key and Clarity filters are used together to improve the visibility of the Milky Way.

Add contrast

Luminar’s excellent Advanced Contrast filter allows you to control the contrast in great detail. Here are the settings I’ve used to give the sky a bit more punch.

Calm down the blues

At this point, I find that the blues in the sky are a touch oversaturated. Therefore I’ve used the HSL filter to desaturate the blues slightly. Just a light touch is needed here..

Brush in the details

As a finishing touch, use the Dodge & Burn filter to brush some detail into the Milky Way. If the effect is too strong, simply reduce the amount slider. I like to brush the detail in using maximum strength so I can easily see the areas I’m affecting, then move the slider back down so the effect is more subtle.

All done!

Below, you can compare the before and after images. With a series of adjustments using Luminar’s powerful filters, it’s possible to create a striking astrophotography look in a matter of moments.

To make things even easier for you, I’ve saved everything we’ve just learned as two Luminar looks – Milky Way Landscape and Milky Way Sky – which are part of my Explorer Luminar looks collection, coming soon to Skylum Store. In just a few clicks you can quickly recreate this same look on your own landscape astrophotography images!
